Currently, I Have Been Dealing With A Saphenous Nerve Entrapment

Currently, I have been dealing with a saphenous nerve entrapment located on my medially on my left knee (not officially diagnosed by a medical professional). I have tried multiple doctors who couldn't figure out that it is a nerve entrapment. What doctor should I go to? A neurologist or an orthopedic? Even if I do go, is there a possible treatment plan that can help because this pain has been occurring for 4 years now.
